ARMSTRONGAppendix (iii)Mechanical Seals in HVAC pumpsComments on inside-installed seals and outside-installed balanced seals.Armstrong’s typical mechanical pump seal is designed with stainless steel metalparts, Viton or EPDM elastomer (‘O’ rings & bellows), carbon rotating face andceramic stationary seat. The ceramic seat is secured by an ‘O’ ring in somepump designs and flat gaskets in others. Each is well suited to the specificneeds of the pump.Mechanical seals are generally referred to as ‘leak proof’. Mechanical seal facesare very flat (Seal faces can be ground and polished [Lapped] to a flatness of 1.5Argon light bands) so the gap between them isvery small. Consequently, mechanical seals doleak; yet leak so slowly that water evaporatesbefore collecting sufficiently to be visible. Thefaces must be flat enough to prevent discernibleleakage, yet not so flat as to prevent thenecessary liquid film from entering the gapbetween the faces. A film of liquid between sealfaces is essential for cooling and lubrication. Asa seal rotates, the heat of rotation acceleratesevaporation of the liquid, resulting in a seal thatis virtually leak free.There are two sealing requirements for a mechanical seal to ensure that theliquid stays inside the pump housing and doesn’t leak into the environment. Theareas are typically known as the Primary and the Secondary seals.Secondary sealing is accomplished by the sealelastomer (Usually Viton or EPDM) which is fittedtightly around the pump shaft, preventing liquidfrom migrating along the shaft towardsatmosphere.The two ‘faces’ of a mechanical seal make up the‘primary’ seal. One face (Usually Carbon) rotateswith the shaft and is part of the seal head, alongwith the elastomer and spring(s). The other face(Ceramic seat is typical) is stationary, held inplace by an ‘O’ ring or seal gland plate and gaskets, in the pump casting. Thecarbon ring rotates against the ceramic seat resulting in the Primary seal.As the carbon ring wears from friction, the seal springs (Or bellows, dependingupon the seal design) help push the carbon ring forward and keep it tight againstthe ceramic seat to maintain design tolerances and prevent leakage.Page 1 of 2
